Verify that you really have ABS by looking for the ABS pump an ECU below the brake master cylinder. If it is there there will be short metal pipes that connect it to the master cylinder and it will have a large connector (about 3 inches by 1.5 inches) plugged into it.

The instrument cluster gets the information over the CAN bus from the ABS ECU, so even if the ABS ECU was present and bad the cluster would still light the light for a second when the ignition is switched on, and if it doesn't send messages to the cluster once the car is running it will keep the ABS light on.
